Brief Summary

Few studies have compared the efficacy of ultrasound (US)-guided TAP blocks with Liposomal bupivacaine(LB) versus ropivacaine in reducing postoperative opioid usage in patients undergoing laparoscopic lower abdominal tumor Resection. Therefore, we are conducting this prospective, randomized controlled trial to compare the postoperative analgesic effects of LB and ropivacaine for TAP blocks among patients undergoing laparoscopic colorectal procedures.

Outcome Measures

Primary Outcomes (1)

  • Postoperative opioid use

    The amount of drug used in the postoperative analgesia pump

    3 days postoperatively

Secondary Outcomes (2)

  • Postoperative pain score

    3 days postoperatively

  • Postoperative adverse reactions

    3 days postoperatively

Study Arms (2)

Liposomal Bupivacaine group

EXPERIMENTAL

Liposomal Bupivacaine was used in the group

Drug: Liposomal Bupivacaine

Ropivacaine group

ACTIVE COMPARATOR

Ropivacaine was used in this group

Drug: Ropivacaine

Interventions

After induction of anesthesia, bilateral TAPB was performed under ultrasound guidance. The patients in the bupivacaine liposome group were injected with bupivacaine liposome 133mg(10ml+ 10ml 0.9% normal saline mixed into 20ml)/ point (two points in total).

Also known as: Bupivacaine liposome
Liposomal Bupivacaine group

Patients in ropivacaine group were given 0.25% ropivacaine 20ml/ point (two points in total).

Also known as: Ropivacaine Hydrochloride Injection
Ropivacaine group
